INTERNAL-COMBUSTION ENGINE.

by declare that the following is a full, clear,

and exact description of the same. 1

The invention relates to improvements in internal combustion engines, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the novel construction and arrangementof parts whereby a large and free inlet opening 1s uncovered at regular intervals by a disk valve operating beneath the permanent head of the cylinder, and a sleeve exhaust valve is operated immediately under said disk valve.

The objects of the invention are to increase the efficiency of the internal combustion engine, to provide a simple and readily operated arrangement of valves, and gen- -,erally to devise an engine of durable construction and comparatively cheap to manu facture.

In the drawings, Figure 1 is a vertical sectional elevation of the engine. Fig. 2 is a cross section on the line AB in Fig. 1. Fig. 3 is a cross section on the line C.D in Fig. 1. Fig. 4 is a diagrammatic view, showing theiposition of the valve at the beginning of the suction stroke. Fig. 5 is a diagrammatic view showing the position of the valves at the beginning ofthe compres sion stroke. Fig. 6 is a diagrammatic View showing the position at the beginning of the impulse stroke. Fig. 7 is a diagrammatic view showing the position of the valves at the beginning of the exhaust stroke.

Like numerals of reference indicate cor responding parts in each figure.

Referring to the drawings. 1 is the cylinder encircled by the water jacket 2 and open at the top and bottom and having the inner and outer walls 3 and 4 at the upperend forming the annular recess 5. and the cire eumferential exhaust ports 6 and 7 through said walls leading to. the exhaust passages 8 and 9 through the Water jacket, the outer casing of the Water jacket having at the V Specification of Letters Patent.

11 is the exhaust valve of cylindrical form and having circumferential ports 12 and 13 adapted to register with the ports 6 and 7, the supporting cross bar 14 extending across from side to side just above said exhaust ports, said crossbar havingthe cross grooves 15 and the shaft orifice 16 in the center thereof. The valve 11 is introduced into the annular recess 5 and rotates therein.

19 is the permanent head having the flange 20 secured to the flange 10 and the water jacket 21 and the inlet passage 22 through said water jacket and leading directly over one sideofithe inlet valve 17 said shaft also having the central shaft orifice 23 through said water jacket, the lower side 2 1 of said head extending downwardly to the inlet valve 17 within the sleeve exhaust valve 11, thus completely inclosing and holding sa1 d valves in place.

25 is a hollow shaft rigidly secured to the inlet valve 17 and journaled in the central orifice 23 and extending above said head.

26 is a shaft rigidly secured to the cross bar 14 and journaled'in the hollow shaft 25 and extending thereabove.

27 is the piston operating in the'cylinder 1.

28 is the piston rod.

29 is the crank shaft.

30 is the cam shaft operatively connected withthe crank shaft 29 by the gears 31 and 32.

33 is the crank chamber caslng.

34 is a lug extendinglnwardly from the crank chamber casing.

35 and 36 are rods forming part of the valve gear and supporting the rollers 37. p

38 is a cam contacting with one of the rollers 37, another cam of similar form con- 105 is afratchet arrangement operated from; theprod connected thereto by the link 43.
